Summary

Abraham Lincoln's Upper Forehead Slope measures 7.7° and scores 3.9, higher than 85% of the men on the FaceIQ Labs celebrity wiki and above its ideal range of 0.0 to 2.0°, which only 25% of the men on the wiki measure inside. Leonardo DiCaprio shares the same 7.7° value, while V (BTS) and Cha Eun-woo (ASTRO) sit just above at 7.8°. At the extremes, Jeff bezos records the highest value at 32.7°, and Thom Strijd the lowest at 0.0°. This measurement evaluates how much the upper forehead slopes backward from the rest of the forehead, and a more sloped upper forehead can make the upper face appear more feminine. For context, see Abraham's Nasofrontal Angle and Abraham's Browridge Inclination Angle.
